Q

challenges with categorical classifications - Hopwood et al. (2018) Commentary: The time has come for dimensional personality disorder diagnosis

A
  • No evidence supporting presence of 10 discrete PD categories DSM-V tells you there is
  • Diagnostic comorbidity between 10 PD categories. - if you have 1 PD you often have 2 or 3, if these are distinct categories how can individuals have multiple
  • Within-disorder heterogeneity. - qualitative experience in symptoms differs
  • Few validated interventions for the 10 distinct PD categories.
  • Categorical approach lacks evidence base when compared to trait approach.
20
Q

issues of comorbidity in PD classification, Marinangeli et al. (2000)

A
  • 156 participants (90 women) voluntarily admitted to a psychiatric ward for many interviews
  • Semi-structured clinical interview (SCID-II) for PD classification based on DSM-3 criteria.
  • found huge percentage of people with multiple diagnosis
21
Q

How is the five factor model associated with personality disorders?

A

Psychoticism also considered a dimensional personality trait
(Eysenck, 1952)

22
Q

Meta-analysis on relationship between FFM and PD, Samule and Widiger (2008)

A
  • To be included, studies had to measure all thirty facets of the FFM + all 10 DSM categorical personality disorders.
  • In total, 16 studies were included, comprising 18 independent samples and 3207 participants.
  • found that they aren’t distinct fro eachother
  • clusters have a relationship
  • however not always a lot to distinguish each disorder
23
Q

Dimensional approach to PDs with 5 traits, Widiger & Simonsen (2005)

A
  • Reviewed 18 proposals that could update DSM-3 with a dimensional approach to PD classification.
  • Proposals can be integrated into a hierarchical structure of maladaptive personality traits
  • Theoretically proposed 5 broad traits
  1. Extraversion – Introversion
  2. Antagonism – Compliance
  3. Constraint – Impulsivity
  4. Negative Affect – Emotional Stability
  5. Unconventionality – Closed to Experience
24
Q

Krueger et al. (2012) empirically validated a dimensional approach for use in DSM-5: the 5 traits

A
  • detachment
  • disinhibition
  • antagonism
  • negative affect
  • psychoticism
25
Q

Hybrid approach to diagnosing PD’s, Skodol et al., (2015)

A
  • Criteria A (step 1) = Maladaptive Personality Functioning assessed from 0 (no impairment) to 5 (extreme impairment). Level of personality functioning scale.
  • Criteria B (step 2) = Maladaptive Personality Content
26
Q

relationship between DSM-5 Alternative Model & FFM

A
  • Watson et al. (2013) examined correlations between BFI (FFM), SNAP-2 (Psychoticism) and PID-5 (DSM-5)
  • found they are correlated
  • negative affectivity was highly correlated with neuroticism
  • disinhibition has a strong correlation with conscientiousness (higher you are in one the lower in the other one)
26
Q

DSM-V dimensional approach to PDs, Samuel et al. (2013)

A
  • Archival data of a clinical sample of 370 participants receiving treatment for substance abuse.
  • PD diagnoses in sample – antisocial (58%), borderline (33%) and avoidant (18%).
  • Self-report measures of normal traits (FFM) and a clinical interview (via DSM-4) for PDs.
  • They selected the FFM items from neuroticism trait most characteristic of borderline PD.
27
Q

Suzuki et al. (2017): how similar are traits in FFM and DSM-5 Alternative Model in relationships to key outcomes?

A
  • Administered PID-5 (DSM-5) and NEO PI-R (FFM) and measured life satisfaction, social adjustment and key behaviours (academic grades, drinking habits).
  • created profiles of similarities and then how the profile corresponded between the normal trait and maladaptive trait
28
Q

Suzuki et al. (2017): do FFM traits and DSM-5 Alternative Model traits show similar temporal consistency?

A
  • test-retest score are high for adaptive and maladaptive scores over time
  • this show maladaptive traits are consistent over time which is a requirement for clinical diagnosis
28
Q

Clinical Utility of Dimensional Classification, Ahmed et al. (2013)

A
  • compared taxonic vs. dimensional classification of schizotypal PD (cluster A) on key outcomes.
  • Two large and national samples from UK and US.
  • Participants completed the structured clinical interview for DSM-IV
  • comparison of taxonic vs. dimensional classification of schizotypal PD on key outcomes.
  • dimensional approach that looked at severity of scores
  • found they were all significant
  • there was a higher correlation for the dimensional approach
29
Q

Clinical Utility of Dimensional Classification, Anderson et al. (2014)

A
  • compared taxonic vs. dimensional classification of borderline PD (cluster B) on key outcomes, including self-harm, antisocial, and risky sexual behaviours.
  • Clinical sample – 167 newly admitted US patients to a psychiatric ward.
  • University sample – 399 students in the US.
  • Administered PID-5 for maladaptive traits (DSM-5) and BPD section of DSM-4 Axis II personality questionnaire (SCID-II-PQ) in both samples.
  • In both samples, categorical (taxonic) and dimensional maladaptive traits were correlated with key outcomes.
  • In both samples, the dimensional maladaptive trait model tended to perform better than the categorical model

Q

what are the advantages of the DSM-5 Alternative trait model? (Krueger & Makron, 2014)

A
  • Empirical model that extends knowledge of FFM into maladaptive personality traits.
  • It predicts clinical outcomes above and beyond categorical classification
  • More in accordance with the complexity of syndromes observed in clinical practice.
  • Finer analyses can be made of the patient characteristics.
